Ethanol plants seek enhanced efficiency with Enogen® corn

• Siouxland Ethanol and Golden Grain Energy to trial Enogen® grain from Syngenta
• Enogen corn designed to deliver improved efficiency in dry-grind ethanol production
• Plants to begin trials in the spring of 2013 and pending results will negotiate a commercial agreement with Syngenta

Syngenta in North America announced that it has signed trial agreements with Golden Grain Energy (GGE) of Iowa and Siouxland Ethanol of Nebraska to demonstrate the value of Enogen® grain. Both ethanol plants will complete a three-month trial with the specialized corn grain bio-engineered to allow ethanol production to be more efficient, cost effective and better for the environment.

Enogen grain is the first genetically engineered output trait in corn specifically for the ethanol industry. Enogen corn expresses the alpha amylase enzyme necessary for dry grind ethanol production directly in the endosperm of the grain. This breakthrough technology eliminates the need to add liquid amylase and can lead to dramatic increases in throughput while potentially reducing costs in energy, gas and water usage.

“We’re glad to be partnering with these plants and we’re excited about the improved efficiency Enogen technology can deliver,” said David Witherspoon, head of renewable fuels with Syngenta. “We’re looking forward to working closely with each plant during the trial to demonstrate the value Enogen technology can add to their operation and their community.”

Golden Grain Energy and Siouxland Ethanol will begin their trials in the spring of 2013 with Enogen grain harvested from acres planted this past growing season. Following the trial, each plant will analyze data to discover the efficiencies created from Enogen trait technology. Pending trial results, each plant will then enter into negotiations with Syngenta to sign a commercial agreement.

When a commercial agreement is in place, Syngenta will partner with the ethanol plants to contract with local growers to supply each plant with Enogen grain. Growers under contract to produce Enogen grain follow simple but specific production and stewardship protocols. In exchange, they are paid a price premium for each bushel of the Enogen grain delivered to the ethanol plant.

“We believe Enogen corn is truly a win-win technology,” said Witherspoon. “The premium paid to each grower for each bushel of Enogen corn produced helps create substantial value and profit potential for their operation as well.”
